Jrifedptry FM Radio Receiver Module 87-108MHz Frequency Modulation Stereo Receiving Board with LCD Digital Display 3-5V PLL

1. the use of advanced digital audio signal processing () and FM modulation phase-locked loop (PLL) to make sound more realistic, more stable performance, long working hours without frequency offset 3. Built-in 30 digital volume adjustment button operation can be easily done, automatic power-down memory data before the power failure,speaker / headphone output automatic switching, quartz crystal frequency stabilization, the temperature change is no longer receiving frequency drift 4. The professional audio audio signal analysis and processing, automatic mute no signal or weak FM signal noise floor of the big time, away from the traditional FM radio signal or the signal is weak in the absence of annoying when rustle, digital incremental rotary encoder to adjust the volume and frequency of use feel good, precise positioning, stable and , 360 ° rotation without dead ends 2. LCD display is more intuitive and accurate, with a very low power consumption and minimal noise, Can search for radio stations and store radio function, easy to operate 5.30-level digital volume adjustment range, Support for serial communication control, use other computer or device control MCU module with serial full functionality
